I bought one when my mare came back off loan and was being a pain to load! I only used it a couple of times and then she was fine to load again! I still have it in the bottom of my trunk if you want it?
I have one of these and thought (and still do think) it is great, at the moment it is a little redundant as my horse is a little too bright and has realised that I don't have the same leverage as a lunge rope. Didn't help that the baggage managed to break one of the d ring thingis which is when she realised that it wasn't a lunge rope!!
I have one for sale on ebay at the moment. It ends tomorrow but I will end the listing and sell if anyone wants it as there are no bid yet. Please PM me if interested!
